<str<strong>on</strong>g>Oracle</str<strong>on</strong>g> Statspack Feature<br />
•Statspack is a diagnostic tool for instance-wide performance<br />
problems<br />
•It also supports applicati<strong>on</strong> tuning activities by identifying high-load<br />
SQL statements.<br />
•It can be used both proactively to m<strong>on</strong>itor the changing load <strong>on</strong> a<br />
system, <strong>and</strong> also reactively to investigate a performance problem.<br />
•To use Statspack you take a number of ‘snapshots’ of the <str<strong>on</strong>g>Oracle</str<strong>on</strong>g><br />
performance data <strong>and</strong> you can then report <strong>on</strong> any pair of these<br />
snapshots.<br />
•The greatest benefits are seen when there is ‘baseline’ performance<br />
data available for the system to compare with current data.<br />
